Product details
Overview
PESD3V3V1BCSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) ultra-small leadless package, designed to protect one signal line against IEC 61000-4-2 ESD (±27 kV) and IEC 61000-4-5 surge (7.1 A, 8/20 µs), with 3.3 V reverse standoff voltage, 8.5 pF typical capacitance at 1 MHz, and 8.9 V max clamping voltage at 7.1 A.
For engineers reviewing the PESD3V3V1BCSF datasheet, PESD3V3V1BCSF pinout, PESD3V3V1BCSF application, or PESD3V3V1BCSF equivalent, this device is selected for high-speed interface protection where ultra-low capacitance, sub-1 nA leakage, and low clamping voltage are critical in portable and consumer electronics.
Technical Context
This bidirectional TVS diode uses dual-cathode symmetric structure (K1/K2) to clamp both positive and negative transients without polarity dependence, enabling protection of AC-coupled or bipolar signal lines such as USB D+/D−, HDMI, or MIPI lanes. Its dynamic resistance is 0.17 Ω at 10 A, ensuring rapid voltage suppression during fast ESD events.
The device operates within −40 °C to +125 °C ambient range and is rated for 150 °C junction temperature. It is not intended for DC-biased lines - its design assumes signal swings centered near ground, with no DC supply connection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected line |
| Clamping Voltage | 8.9 V max at 7.1 A (8/20 µs) - peak voltage seen by downstream IC during surge; limits stress on sensitive receivers |
| Diode Capacitance | 8.5 pF typ at 1 MHz, 0 V - preserves signal integrity on high-speed interfaces (e.g., USB 2.0, eMMC) without distortion |
| ESD Rating | ±27 kV contact discharge (IEC 61000-4-2) - exceeds Level 4 immunity requirements for handheld and portable devices |
| Leakage Current | <1 nA at 3.3 V - avoids loading of high-impedance analog or RF signal paths; negligible power loss in battery-powered systems |
| Package Dimensions | 0.6 mm × 0.3 mm × 0.3 mm - enables placement directly at board edge connectors with minimal PCB area and parasitic inductance |
Pinout & Package
DSN0603-2 (SOD962-2) is a 2-terminal, leadless, ultra-small surface-mount package with 0.4 mm pitch, 0.3 mm height, and exposed copper terminals for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Forms one half of symmetrical bidirectional clamping path; connects to protected line for negative transient conduction |
| 2 | Cathode (Diode 2) | Forms second half of symmetrical clamping path; connects to same protected line for positive transient conduction |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Enables single-device protection of AC-coupled or differential lines without polarity constraints or external biasing |
| Ultra-low 8.5 pF capacitance | Maintains signal rise/fall times & bandwidth on interfaces up to 480 Mbps (USB 2.0) without measurable degradation |
| 0.3 mm profile | Allows co-placement with micro-B/USB-C connectors and fine-pitch RF modules without mechanical interference |
| Sub-1 nA leakage | Prevents DC offset drift and battery drain in always-on sensor interfaces and low-power wake-up circuits |
| 0.17 Ω dynamic resistance | Minimizes voltage overshoot during nanosecond-scale ESD pulses, reducing risk of latch-up in adjacent ICs |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESD9B3.3ST5G | Higher clamping voltage (12 V max at 7.1 A); 12 pF capacitance; SOD-923 package (0.8 mm × 0.6 mm) | Less suitable for >200 Mbps interfaces due to higher capacitance; better surge handling margin (12 A IPPM) | Select when surge robustness outweighs speed; avoid for USB 2.0 or MIPI where <10 pF is mandatory |
| Vishay ESDEFL03-2 | Lower capacitance (5 pF); 3.3 V VRWM; but unidirectional configuration requiring external bias network | Requires additional components for bidirectional operation; not drop-in compatible | Choose only if system allows redesign for active biasing and absolute lowest capacitance is required |
Compared with ESD9B3.3ST5G and ESDEFL03-2, PESD3V3V1BCSF delivers optimal balance of ultra-low capacitance, true bidirectionality, and compact footprint - making it preferred for space-constrained, high-speed portable interfaces where layout simplicity and signal fidelity are non-negotiable.

FAQ
Can PESD3V3V1BCSF be used on a DC-biased signal line?
No. The device is explicitly designed for AC-coupled or ground-centered bidirectional signal lines. Its dual-cathode structure requires the protected line to swing symmetrically around ground. Connecting it to a DC-biased line (e.g., 3.3 V I/O) risks forward conduction, excessive leakage, or premature failure per Section 10 of the datasheet.
What is the recommended PCB layout for optimal ESD performance?
Place PESD3V3V1BCSF within 2 mm of the connector entry point, route the protected trace directly to pins 1 and 2 with minimal stub length, use a solid ground plane beneath the device, and connect the ground return path to the system ground with ≥2 vias ≤1 mm from pin 2. Avoid routing unprotected traces parallel to protected ones.
Does PESD3V3V1BCSF meet automotive AEC-Q200 requirements?
No. This device is not AEC-Q200 qualified. Nexperia's official documentation states it is intended for consumer, computing, and communication applications - not automotive environments. For automotive-grade ESD protection, refer to Nexperia's Automotive Qualified PESDxUSB30 series.
How does the 0.17 Ω dynamic resistance impact system-level ESD immunity?
This low Rdyn ensures minimal voltage overshoot during the initial 1–3 ns of an ESD event, reducing the peak stress on downstream ICs. Measured TLP data shows clamping remains below 7.5 V at 8 A, directly lowering risk of gate oxide rupture or CMOS latch-up in sensitive PHYs and SerDes blocks.
